Question

What are the molar heat capacities of: H2O(l) NaCl and Tungsten? I got
75.32 J/K*mol 50 J/K*mol 24.8 J/K*mol

Answer 1

I don't know how accurate you need to be. I convert 4.184 J/*g for H2O to J/mol by moltiplying by 18.015 and it is 75.37. For W I found 24.8 and for NaCl I found 86.4 J/100 g which would be
86.4/100 x 58.44 = 50.49 J/mol*K.

Answer 2

Okay thank you, I was close.

Answer 3

I don't know how good these sites are about providing accurate information.
